A new preprint establishes that generating synthetic data under differential privacy is fixed-parameter tractable (FPT) when parameterized by the treewidth of the query family's incidence graph. The authors introduce two algorithms that achieve optimal error rates: one based on linear programming and the FPT of the LP dual's separation problem, and another using a subsampled private multiplicative weights method with FPT Gibbs sampling. Both approaches are unified by a dynamic programming framework over tree decompositions.
